APPARATUSFOR ROLLING CAR-AXLES.

SPECIFICATION forming part of Letters Patent No; 698,071, dated April 22, 1902. r

Application filed March 6,1900. Renewed August 24, 1901. Serial No. 73,173. (No model.) I

To all whom it may concern:

Be it known that I, CHARLES STEELE, a citizen of the United States of America, residing at Duquesne, (post-office box 653,) in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Rolling Car- 1 Axles; and I- do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, whichform a part of this specification.

My invention relates to an improved apparatus for rolling car-axles; and it consists in three rolls arranged in suitable housings,'to gether with certain details of. construction and combination of parts, as will be fully described hereinafter. 1

In the accompanying drawings, Figure lvi's an end sectional elevation of my improved apparatus for rolling 'car-axleswhich is constructed andarranged in accordance with my invention. Fig. 2 15a front elevation of the same having the lower front roll removed from the housing and showing a finished axle therein. Fig. 3 is an enlarged end elevation of the top or eccentric roll. V To construct an apparatus for rolling axles in-accordance with my invention, I provide aset of housings 1 of a suitable size and form of construction and arrange in proper -bear-, ingstwo rolls 8, the one parallel to the other and both upon the same plane. I Each of these rolls 8 is formed with an enlarged middlepor tion to form the reduced central part of the axle 12 and at points near each end with collars 9 to form the journals 13ofthe-said axle.

.4 I ing-line'of the two lower rolls 8. This'roll 3 Operating in connection-with these two rolls 8 is a large eccentric roll 3, located and arranged in bearings l dire'ctly'above the dividis formed. with aneccentric portion 4,1which operates in conjunction with the enlarged I with segmental integral collars 6, which operate to form the journals 13. of the said axle. 1 This roll 3 is alsoformed with a fiatportion -or side 10, which when turned down willperportions of the lower rolls 8 ,toform thereduced center of the axle12, and is alsoformedmit the operator either to remove the finroll 3 is now given a slow powerful rotary movement, and the eccentric part 4, engaging with the said bar, rotating it, together with the lower rolls 8. This rotary movement of the partswill cause the eccentric part 4 to reduce the metal at the center of the bar, and

when this has been accomplished the collars '6 and 9 byreason of their rotary movement will roll the journals 13, thereby completing the axle, which may be removed whenthe' flat side 10 is down. Various slight modifications and changes may be made in i the details of construction 1 .WllillOlll] departing from the spirit of the invention. v r

Having thus described my invention, what I claim, and desire ent, is I V The combination with the' housing and a l rolls tapering from their center toward each I end and carrying collars at the end of the ta- 1- pair" of lowerrolls journaled therein, said to secure by Letters Patper,of an eccentric' roll having a flat face,

and of relatively greater diameter than the lower. rolls, said eccentric roll beingjournaled in the housing above the dividing-line of the lower rolls and being tapered from its,

centerftoward each end, and segmental collars secured on said eccentric ,roll, said collars having one end terminating at the flat face ofthe roll, as'and forthe purpose-speci-v In testimony whereof I have hereunto affixed my signature in thepresence of .twosubl l I scribing witnesses.
